Brake issue driving me mad

That's not looking like the brakes. It's looks like a transmission problem to me. How's the VCU and IRD?

That was when vcu was on its now off and the judder is about half that now. Don't think can get that in vid to be honest as its not as bad as that now

Fook me! Thats nasty. I'd go with @Nodge68, transmission or mounts.

I'm thinking IRD failure tbh. Especially if it's less with the VCU removed. I'd be draining the oil out for a look. I'd be surprised if it's not full of metal chunks.

Engine mounts? That was with vcu on and after about 40 min drive not straight away its when it gets warm. No where near that bad now but still getting that but lot less aggressive. So change the cv joints

@Nodge68 oil was changed 2 weeks back as specialists and was no sign of parts or metal in there. I know the ird can be removed and blanked off. So what are other signs that its ird as can look for it.

That's not cv joints. If it ain't doing it when it's cold and starts doing it when it warms up, it's probably the IRD.
Because when cold your fluid is thick, so little movement, as it warms up and becomes thinner you get alot more movement.
Do an ird oil change now!

Edit, did they put the right oil in as I've just read your reply.

They did they are very good honest guys. I'm getting the shake judder from cold now as was under the impression it was the central prop and the charm of a 4x4 as this is my very first one. Sorry not explaining my self great at times so apologies on that. The shake is in 2nd & 3rd from cold

Unfortunately my speciality is with auto boxes not manuals. So I'll have to leave this one, sorry.

Well vcu is fooked. But I'm stumped hope it's not the ird but the luck im having with this car will be. Any other signs to look for to give a accurate diagnosis that it's the ird? Though it's cause the breaks where doing something and heating up but looks like was massivly wrong

I'd love to investigate this myself. I had a similar problem on a V6 with similar symptoms, except it was doing it hot or cold. On the V6 it was most evident between 15 to 35 Mph. I never actually managed to solve what was the cause of that vibration. However I suspected it was IRD related. Everything except the gearbox and IRD was changed, including the drive shafts.

Well I'm in Cumbria if your not far way more yah welcome to

15/35 is about the same as what I'm getting now hot or cold. As of yesterday that is when shaft was removed. The ird is a ration box so if something had gone would suspect it to be jamming not messing properly etc

Hi all
Getting issue with front breaks getting stupidly hot on short runs.
I've changed the slide pins
Changed caliper pistons and seals
Bleed the breaks getting better but not great there seems to be no binding but slight rub from the disc on the pads now would this put a lot of heat in to the discs in a mile drive? Getting discs tomorrow anything else I should check?

Sorry for being pedantic but I keep seeing the heading for this post and because you've spelt "Brakes" as "Breaks" its seriously affecting my OCD. Any chance you could correct it so that I can relax for the weekend?
Thanking you in advance

Yeah sorry mate dyslexic rely on auto correct to much

@Nodge68 @Skinny Mike
Been out for a drive just got back now from it.
Results are constant juddering at all speeds lucky where I live fast winding roads and what I've found is right corners it's worse left corners is disappears briefly so I would assume this is the left hand drive shaft. The brakes are still roasting so that's still a issue think that will be just new calipers. I love and hate this car at the time

Other end of the country to me then.
Try grabbing the both inner CV joints and wiggle them, up and down, left and right. There will be some play but it shouldn't feel loose. If they flop about then it's likely to be the output bearings in the box or IRD. The IRD bearing is reasonably straightforward to do for a good machanic. Sadly the gearbox side requires much more work to change.
If you are changing the drive shafts, don't buy cheap. The best are the original manufacturer's parts. Most cheap replacements vibrate anyway.

so if it's the shafts the ird bearing needs to be changed as well?

Just been under the old girl and it's cold there is play but nothing drastic the play is about equal on each side. Going to mount my GoPro under the car and go for a drive see what is happening I should not wobble should it. Will post findings up and see what you think.

As some one suggested earlier in this post about brake pedal adjustment I've looked at it and there is no way it can be adjusted from in side the car at all. How do I check adjustment? Disc now getting hotter quicker

2 things to check. When you turn a hub, how much run out (sideways movement) is visible at the disc edge. The gap between the pads is a good place to look. There should be no visible run out. If the edge of the disc looks wobbles like a buckled bicycle wheel, then the discs are fubared.
Look at the lower engine tie bar, the large end and check for softness of the bush. Try levering it to see how much slop it has. Softness here can allow the engine to shake about.
